Will the laptop dock/other docks be worth the money?

Will the laptop dock/other docks be worth the money?

Now that we know the prices on the docks, are they really going to be worth paying that much for them? I think if you have a phone that can do all the things without a dock that you can with..... Why buy the dock? Don't get me wrong, I think they are awesome and the idea is very cool, but can wait till I can hack the phone so I can use tethering after that time comes. Any oppinions?

"if you have a phone that can do all the things without a dock that you can with....."

For me, this is the rub. Today's announcement seemed to imply that you can only use the Firefox browser and webtop via a dock. I'm looking for confirmation that you can still use the full browser simply by plugging a monitor into the phone's HDMI port directly.
